A. 9 Let the brother of low degree rejoice in that he is exalted:
10 But the rich, in that he is made low:

B. because as the flower of the grass he shall pass away.

C. 11 For the sun is no sooner risen with a burning heat,

B’. but it withereth the grass, and the flower thereof falleth,
and the grace of the fashion of it perisheth:

A’. so also shall the rich man fade away in his ways.

Note: here is a strong echo of the parable of the sower.
